Test Case:
1. Add DISTRO_FEATURES += 'pam' to local.conf and build image with
   quagga.

2. On target:
1) cat /etc/pam.d/guagga
#
# The PAM configuration file for the quagga `vtysh' service
#

# This allows root to change user infomation without being
# prompted for a password
auth		sufficient	pam_rootok.so

# The standard Unix authentication modules, used with
# NIS (man nsswitch) as well as normal /etc/passwd and
# /etc/shadow entries.
auth       include      common-auth

2) add option debug to pam_rootok.so
 auth	    sufficient	pam_rootok.so debug

3) pam_rootok.so
run command vtysh as root, enter qemu0#:
root@qemu0:~# vtysh 

Hello, this is Quagga (version 0.99.21).
Copyright 1996-2005 Kunihiro Ishiguro, et al.

qemu0# 
log info in /var/log/message(or /var/log/auth.log) shows pam_rootok.so return success:
2013-11-08T03:33:44.898360+00:00 qemu0 vtysh: pam_rootok(quagga:auth): root check succeeded

4) pam_unix.so
the content of common-auth are shown at section "Common configure files"
comment the configure file quagga pam_rootok.so line, because it will make pam return success:
 #auth		sufficient	pam_rootok.so
and modify the pam_unix.so line in common-auth to remove nullok_secure:
 auth	[success=1 default=ignore]	pam_unix.so debug

5) run commands with invalid password:
root@qemu0:~# vtysh 
Password: 
root@qemu0:~# 
log in /var/log/message(or /var/log/auth.log):
2013-11-08T04:20:49.418763+00:00 qemu0 vtysh: pam_unix(quagga:auth): authentication failure; logname=root uid=0 euid=0 tty= ruser= rhost=  user=root
